ABSTRACT:
A guide mechanism for a weft thread inserting gripper rod in shuttleless looms, has upwardly open U-rail mounted in a gripper rod housing for guiding at least a portion of the reciprocating gripper rod in the housing. Additionally, guide rollers position adjustably mounted in a bracket are located in an operating position for guiding the gripper rod outside the gripper rod housing. The bracket is either tiltably or removably mounted to the loom frame for bringing the guide rollers into an inoperative position in which the gripper rod is easily accessible for disengagement from its drive sprocket and removal out of the gripper rod housing. The guiding by the U-rail and by the guide rollers effectively prevents gripper rod vibrations, yet permits an easy access to the gripper rod.
